Django admin list_filter custom field error

I extended the user with extra option, such as department. But when i try adding filter for the derpartment at the admin panel. It throws this error:

ERRORS: : (admin.E116) The value of 'list_filter[0]' refers to 'department', which does not refer to a Field.

Refrence to how it looks: https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#extending-user

With this addition:

class UserAdmin(BaseUserAdmin):
inlines = (EmployeeInline, )
list_display = ('username', 'email', 'first_name', 'last_name', 'get_department')
list_filter = ('department',)

def get_department(self, instance):
    return instance.employee.department

List display seems work fine.

User model has relationship with Employee Model so you can access it From user Table with employee field. employee is now the field of user.

list_filter = ('employee__department',)

employee is the Model. and department is the field of Employee. hopes it should work for you My one is working below is the screen shot the that.

this is my model Screenshot check it out.

this is admin screenshot and filters

and this is the final resutls

You have to specify which model department is in.

list_filter = ('employee__department',)
